Grid Guardians is a deep strategy game where every move counts. Set inside a futuristic computer system, players deploy 'Guardians' to combat malicious viruses. Each Guardian has a unique movement range and set of abilities that can interact with the environment or other teammates. Success depends on positioning, managing your 'Energy' pool, and predicting the enemy's AI behavior in tight, grid-based arenas.
Pushing an enemy into a 'Data Leak' tile will deal double damage and stun them for one turn. Always check the grid for hazards before moving.
Combine the 'Shield Guardian' with the 'Blaster' unit. If the Shield Guardian is adjacent to the Blaster, all projectiles gain a power boost.
Matches are designed for mobile play and usually last 3 to 5 minutes.
